Answer:
a. Extinction Burst.
Step-by-step explanation:
Extinction burst occurs when a reinforced behavior of the past increases when the maintaining reinforcer is removed. In other words, we can say extinction burst has to do with behavior elimination by the removal of what reinforces it.
For example, if a child had always gotten a sweet to calm him of his tantrum, but this time around, the parents stopped giving sweet, because the conditioned response is no more yielding results; when the child notices the sweet is not given anymore, the child is forced to stop his tantrum. This is a classic example of extinction burst.
In order to control extinction burst in children, consistency and patience are key.
